This example demonstrates how VizHub projects can load external libraries and organize code into reusable modules. It loads D3 v5 from UNPKG and uses the `select` function to target a `div#message` element, setting its text content from a locally imported ES6 module. The `myMessage.js` file exports a simple string, while `styles.css` centers the text in a twelve-em font size. The result is a minimal hello-world that shows D3’s import syntax and local module architecture.
